The Renewable Energy Component of the Indo-German Energy Programme (IGEN-RE) is a bilateral cooperation project with the Indian Ministry of New and Renewable Energy (MNRE) carried out by the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) on behalf of the German Federal Ministry for Economic Cooperation and Development (BMZ). Launched in 2010, the project aims to promote renewable energy in rural areas. For more information please visit our website: www.igen-re.in.

Water is running through irrigation
channels to the fields where vegetables, maize, mustard, wheat and other crops
of Vaishali farmers are being cultivated. The water is supplied by Vaishali Area Small Farmer Association (VASFA)
– which has been supporting irrigation groups since over 40 years, providing
more than 700 farmers with water from their diesel powered pumping systems in
exchange for a monthly membership fee and an additional amount paid for water on
an hourly basis. Recently, however, the usual loud pounding of the diesel pump
has fallen silent.

The
GIZ initial study titled “Solar
Water Pumping For Irrigation” highlighted that low awareness about the
technology among farmers and financial institutions, who can play significant
role in the development of market for solar water pump by providing consumer
finance, is a major challenge. Renewable Energy
Component of the Indo German Energy Programme (IGEN-RE) of Gesellschaft für
Internationale Zusammenarbeit (GIZ) GmbH hired the service of Claro Energy a private company providing off-grid
solar solutions, to replace two diesel pumps with solar powered ones.At these demonstration sites, diesel pumps,
which were being operated by two VASFA groups, were replaced by solar water
pumps, and the tariff collected by these groups will contribute towards upfront
costs of replacement for the remaining groups.

Currently, farmers whose land are located
outside VASFA’s catchment area either own private diesel pumps or rely on
renting pump sets on an hourly basis. The former option is expensive,
especially due to high maintenance and operating costs. About INR 3000 are
spent by each of the farmer on diesel alone in the seasons of Rabi and Kharif.
For renting a pump set for one hour farmers in the area pay INR 120 making
rented pumps an equally expensive as
well as unreliable source of irrigation. “Getting water from an institution,
such as VASFA, instead of private individuals”, Ram Chandra Thakur (62) says, “would
give us more security concerning water access. Solar pumping would furthermore
help us to save on irrigation cost.”

Educating farmers about solar pumping
technology, includingoperation and
maintenance as well as technical features, such as output and operating times, is
one of the main goals of the demonstration sites. About 250 farmers will visit
the site(s) each year and attend the workshops and information sessions where
their questions related to solar pumping will be answered. Simultaneously,
these events will give solar companies the opportunity to gain a better
understanding of their customers’ preferences and choices relating to the
technology. In addition, the presence of bankers, NGOs and government agencies
will be an integral part of these events giving them a better understanding
about the technology as well as the obstacles faced by farmers interested in converting
to solar. “The planning and installation of the two solar pumps has been a very
enriching experience” highlights Nilanjan Ghose, technical expert of IGEN-RE. The
sites for replacement of the two pumps were selected democratically involving
all the irrigation groups under VASFA. The installation of the solar panels was
customized to ensure minimum blocking of agricultural land. Santosh Singh,
technical expert of IGEN-RE explains: “we hope that these demonstration sites
will aid in educating and awareness raising amongst all stakeholders concerned,
paving the way for similar installations and finally leading to a broader
market-based uptake of the technology in Bihar”. GIZ is working towards development
of market ecosystem
for solar water pumps.
